köken: Inherited from Old French halaigre, from Latin alacrem (“lively; happy, joyful”). The Old French form alegre derived from a Vulgar Latin form *alacrum, and the form (h)aliegre from an *alĕcrum. The transition of Latin -cr- to French -gr- is paralleled in aigre, maigre; it may have been influenced partly by Old Occitan alegre. Doublet of allegro. More at Italian allegro.
köken: From Old Japanese. First cited to the Man'yōshu of circa 759 CE. A surface analysis suggests that this might be derived from 熟れる (ureru, “to ripen, mature”) + しい (shii, “adjective forming suffix”). However, it is unclear how the sense of "feeling mature" would match the sense of "glad".
köken: First attested in the Seokbo sangjeol (釋譜詳節 / 석보상절), 1447, as Middle Korean 깃브다 (Yale: kìs-pù-tá). Originally Middle Korean 기ᇧ다〮 (kìsktá, “to rejoice”) + -브- (-pù-, adjective-deriving suffix), hence literally "rejoiceful; rejoice-worthy", but the original verb is obsolete and the word is now perceived as monomorphemic. 기껍다 (gikkeopda) is from the same etymon.
